Know of any good alcoholic drink mixes?

I recently learned of one called "Flaming Dr Pepper".

Take a shot glass, fill it 3/4 wih Amaretto and 1/4 with Bacardi 151 set it in a beer mug and fill the mug with beer till the servace just gets to the surface of the shot glass. Take a grill lighter and light the top of the shot glass on fire. Let it burn for a few seconds, blow it out then chug the whole thing while thr shot glass is still in the mug. It's supposed to taste just like Dr Pepper if done properly.
